Characteristics: Thorlin is Pro Alliance. He HATES the Horde. He is a very optimistic character but is ruthless when on the battlefield. He rarely comes out of his tank during combat as he prefers to destroy foes with the power of his tank the "Thunderhammer". He is an extremely intelligent engineer and a veteran of The Second and Third wars. He firmly believes that the Horde has no place in Azeroth. He is extremely rich and very generous to his friends.

Being the fourth child and only son of his old and dieing father, young Thorlin was given the family mines and land in Dun Morogh upon his fathers death. The family lands and mines had been in disarray as his father had grown older due to the fact that he had no sons to help him manage the lands and by the time the old Thunderhammer had died a good deal of the family's real estate and capital goods were in ruins. Knowing well the problems of not being able to manage the mining company that his family had started, young and with the money that family had left, Thorlin hired engineers and scholars to teach him the ways of engineering and the world. Within a decade Thorlin turned his family's fortunes around.

During the Second war when the orcs pressed north into Dun Morogh, the Thunderhammer family mines were one of the main contributors of metals and ores to the alliance. High in the mountains of Khaz Modan the Thunderhammer mines were never found by the Horde. Spewing out the life blood of the alliance, Thorlin, now an adult became extremely wealthy supplying the alliance. Thorlin himself enlisted in the war and left his sisters to watch over the mine while he was away. Because of his engineering experiences and his nobility he was given command of a tank battalion and named his tank the "Thunderhammer" which became legendary for the larger caliber of its cannon which Thorlin himself installed. Even though Ironforge itself was besieged, Thorlin and his tanks staged guerrilla operations against the Bleeding Hollow Clan. Here is where Thorlin became friends with a gnome pilot by the name of Welby Thermojet. With the help of Thermojet and his planes and knowing the mountains better than the orcs, Thorlin and his forces managed to slip away every time into the deep mountains of Khaz Modan. After Ironforge was liberated by the Alliance, Thorlin and Welby assisted in the assault of Blackrock Mountain and the assault of the Dark Portal. During these battles Thorlin met an alliance knight by the name of Sir Walter Delbath of Stromgarde. Sharing a hatred of the horde and both being noble and business men before the war, Thorlin and Sir Walter spoke much together and became good friends during and after the war.

After the Second War was over, Thorlin and Welby were invited by Sir Walter to Stromgarde on many occasions. The three talked much of business, engineering, and the Horde and how all of the demons should have been put to death rather than captivity. Thorlin and Welby grew to love the nation of Stromgarde and its beautiful lands. During this time short time of peace Thorlin financed a school of engineering and flight and had Welby Thermojet oversee it as the main teacher. The school produced many bright scholars and furthered engineering.

When Ner'zhul and the orcs returned to Azeroth briefly the forces of the Alliance went through the new Dark Portal to put and end to the Horde. Sir Walter stayed behind due a leg injury he received falling from a horse during piece time. Thorlin's mines once again made him extremely wealthy as the expedition required weapons and armor made from the mountains of Khaz Modan. Neither Thorlin or Welby accompanied the expedition to Outland. Welby stayed behind as the master of the engineering school and Thorlin stayed and managed his mines. The two would continue to see Sir Walter from time to time in Stromgarde.

When the Third War erupted the three companions were once again sent out to war. Thorlin enlisted Welby and Sir Walter to be in his battalion. The three fought in Lordaeron against the Scourge and in Hyjal against the Legion. Thorlin's "Thunderhammer" once again became legendary for its destructive capabilities. Thorlin's mine also capitalized on the Third War making him one of the richest dwarves on Azeroth.

After the Third War Sir Walter returned to Stromgarde and his family farm while Thorlin and Welby returned to the mines and the school. While Thorlin's mine and school prospered Sir Walters farm did not. Stromgarde had been on the decline as an empire for some time. With Danath Trollbane and the majority of what was left of the Stromgarde army in Outland, the city itself fell prey to ogres and syndicate and was lost. Sir Walter wrote to Thorlin telling him of the dire straights that his nation was in. He wrote of the bandits controlling the highways and of the Horde in Hammerfall. He wrote that on many occasions that his farms had been looted by thieves in the night and that he feared that soon the entirety of the Arathi Highlands would fall to the Horde or the Syndicate. He wrote of the Alliances lack of aid and how the people of Stromgarde had been abandoned by those they fought for not even a decade ago. He wrote of the Forsaken's march across the Hillsbrad Foothills and how he feared that the plagues of the Forsaken would soon be used on his people. Thorlin decided that actions had to be taken to save what was left of the Arathi nation that he knew and loved. With his immense wealth and knowledge of engineering Thorlin began to make an army.

Thorlin bought hundreds of old unused tanks, artillery and airplanes that had been decommissioned from the Third War. While the rest of the World fought in Outland and Northrend his school of engineering upgraded and retrofitted each tank and airplane to make them better than ever and more powerful than the current models used by the alliance. He gathered old veterans that he had fought with before who no longer wished to be in the political nonsense the Alliance had become. These old veterans were taught to pilot the tanks and airplanes with ruthless skill. He wrote to Sir Walter and told him to gather all the Knights that he could and send them to Khaz Modan for arming and training. With hundreds of tanks, airplanes, artillery and Knights Thorlin's army was becoming a fighting force unlike any the world had ever seen. This army would be totally mechanized. It would be fast, decisive, and powerful.

As preparations neared their end and the army was nearly complete in training and building, Thorlin sent out one last letter to inform Sir Walter of his progress. He told Sir Walter that he would soon be seeing the "Thunderhammer" outside of his home with a glorious army.
